v2.0.0 — modern ESM-only rewrite

First major in years: a from-scratch modernization of floatify with zero runtime dependencies.

⚠️ Breaking changes

• ESM-only. floatify is now a native ES module (export default). Use import floatify from "floatify"; require() is no longer supported (CJS consumers on Node ≥ 22.12 can use require(esm)).
• Node ≥ 18 required.

What's changed

• Rewritten in modern ES6+ (no Babel — Node runs it natively). The parsing algorithm is unchanged; all 281 test assertions pass.
• Test suite migrated to the built-in node:test runner — mocha + c8 removed, which also clears the serialize-javascript (RCE) and diff (DoS) advisories at the root. npm audit → 0 vulnerabilities.
• eslint flat config; dropped legacy Babel/airbnb-es5/Travis/Scrutinizer setup.
• Published tarball scoped to src/ only.

Usage

import floatify from "floatify";

floatify("123.242,5346556"); //=> 123242.5346556
floatify("123.123", true);   //=> 123.123 (prefer decimal separator)
